Dear Emrah Ersahin,
You are using main-left-right.xml layout, so you can go to your_site\templates\sj_news\layouts\main-left-right.xml and find:
<position class="span3" data-normal="span3" data-tablet="span3" data-stablet="span3" type="feature">@logo</position>
<position class="span5 offset4" data-normal="span5 offset4" data-tablet="span5 offset4" data-stablet="span7 offset2" style="none" type="modules">position-0</position>
=>
<position class="span12" data-normal="span12" data-tablet="span12" data-stablet="span12" type="feature">@logo</position>
<position class="span5 offset6" data-normal="span5 offset6" data-tablet="span5 offset6" data-stablet="span7 offset4" style="none" type="modules">position-0</position>
Thanks
